You know what upsets me a little bit about Halo 4? The name. It kinda makes it seem like Reach never happened - like it was just a sidestep, like ODST. Which it wasn't.

I think that's exactly why MS are calling it 4. According to VGChartz.com, Reach has sold just over 8 million copies. Which is around the same amount as Halo 2, but over 4 million less than 3. They want people to know that this is the real deal, a continuation of the series and they want to make sure they sell as many copies as possible.
